Abstract

1425634 Light guides LICENTIA PATENTVERWALTUNGS - GmbH 7 Feb 1973 [8 Feb 1972] 5921/73 Heading G2J [Also in Division H1] A semi-conductor laser component comprising a laser active portion 1 and a light-emitting surface, has two oppositely disposed boundary surfaces 2,2' of the portion 1 oriented at an acute angle with respect to each other and converging toward the light-emitting surface. The portion 1 has a refractive index greater than that of the surrounding material 1', and may be semi-conductive, e.g. Ga Al As. In the embodiment, Figs. 7, 8 (not shown) a heterostructure diode comprises an active portion (12) bounded by converging troughs (11) etched in the superposed layers, the walls of the troughs being covered by a layer, e.g. of silica, of lower refractive index.
